Account Update Question

I recently purchased a BlackBerry Classic, unlocked from shopbb. It is running the latest 10.3 os on the Bell network in Canada.

Every night at around 10pm, I get two notifications saying that my Skype and inst10 accounts need to be updated (passwords). I deleted the inst10 app, and even removed it from the BlackBerry World's "my world" memory, yet this continues to happen.

A device restart/reboot did not adjust the issue. I can live with the issue, however might their be a fix for something like this?
